The recent fix for NULL sta in iwl_mvm_get_tx_rate() still has a call of iwl_mvm_sta_from_mac80211() that may be called with NULL sta. Although this practically only points to the address and the actual access doesn't happen due to the conditional evaluation at a later point, it looks a bit flaky. This patch drops the temporary variable above and evaluates iwm_mvm_sta_from_mac80211() directly for avoiding confusions. Fixes: d599f714 ("iwlwifi: mvm: don't crash on invalid rate w/o STA") Signed-off-by:

This element has a very dynamic structure, create a small helper function to validate its size. We're currently checking it in mac80211 in a conversion function, but that's actually slightly buggy.

Split 6G band into 8 sub-bands where indexes are from 0 to 7, i.e. RTW89_CH_6G_BAND_IDX[0-7]. Then, decide subband by both band and channel instead of just channel because conflicts between 5G channels and 6G channels. Moreover, add default case to the existing use of switch (subband).

BCM43454/6 is a variant of BCM4345 which is exactly identical to BCM4345/6, except the chip id is 0xa9be. This patch adds support for BCM43454/6 by handing it in the same way as BCM4345. Note: when loading some specific version of BCM4345 firmware, the chip id may become 0x4345. This is an expected behavior, and it will restore to 0xa9be after power cycle. Signed-off-by:

Eric Dumazet says: ==================== ipv6: remove addrconf reliance on loopback Second patch in this series removes IPv6 requirement about the netns loopback device being the last device being dismantled. This was needed because rt6_uncached_list_flush_dev() and ip6_dst_ifdown() had to switch dst dev to a known device (loopback). Instead of loopback, we can use the (hidden) blackhole_netdev which is also always there. This will allow future simplfications of netdev_run_to() and other parts of the stack like default_device_exit_batch(). Last two patches are optimizations for both IP families. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

This is an optimization to keep the per-cpu lists as short as possible: Whenever rt_flush_dev() changes one rtable dst.dev matching the disappearing device, it can can transfer the object to a quarantine list, waiting for a final rt_del_uncached_list(). Signed-off-by:

IPv6 addrconf notifiers wants the loopback device to be the last device being dismantled at netns deletion. This caused many limitations and work arounds. Back in linux-5.3, Mahesh added a per host blackhole_netdev that can be used whenever we need to make sure objects no longer refer to a disappearing device. If we attach to blackhole_netdev an ip6_ptr (allocate an idev), then we can use this special device (which is never freed) in place of the loopback_dev (which can be freed). This will permit improvements in netdev_run_todo() and other parts of the stack where had steps to make sure loopback_dev was the last device to disappear. Signed-off-by:

The mv88e6352, mv88e6240 and mv88e6176 have a serdes interface. This patch allows to configure the output swing to a desired value in the phy-handle of the port. The value which is peak to peak has to be specified in microvolts. As the chips only supports eight dedicated values we return EINVAL if the value in the DTS does not match one of these values.
